The composite function G(F(x)) = 4√x is for the functions when F(x) = √x and G(x) = 4x.
What is Composition of Functions?Composition of two functions f and g can be defined as the operation of composition such that we get a third function h where h(x) = (f o g) (x).
h(x) is called the composite function.
Given that, the composite function is,
G(F(x)) = 4√x
We have to find the functions G(X) and F(x).
We know that,
G(F(x)) is the function G(x) when x is changed to F(x).
Let G(x) = 4x
In G(F(x)), x will be replaced by F(x).
In order to get 4√x, x is replaced by √x.
So, F(x) = √x
Hence G(x) = 4x and F(x) = √x.

Find the exact value of each variable that represents its side length in a right triangle. Please help me with this ASAP!
Answer:

[tex]k=2.5[/tex]
[tex]m=\sqrt{21}[/tex]
[tex]n=3\sqrt{10}[/tex]
[tex]p=\sqrt{17}[/tex]
Step-by-step explanation:
We can use the Pythagorean Theorem in each case.
Pythagorean Theorem:
[tex]a^{2} +b^{2} =c^{2}[/tex]
Where [tex]a[/tex] and [tex]b[/tex] are two sides of a right-angle triangle and [tex]c[/tex] is Hypotenuse (the longest side opposite to the right angle)
For [tex]h[/tex]:
[tex]h^{2} +8^{2} =10^{2}[/tex]
[tex]h^{2} +64=100[/tex]
Subtract 64 from both sides:

sarah has 214 bag of beads each bag has enough beads for 22 bracelets she estimates that since 200x 20 =4,000 there are enough beads for aT LEAST 4000 bracelets tell how how you can critique sarahs reasoning
Answer:
Sarah's reasoning sounds good to start. She rounded the available bags and their content, so the result, 4000 bracelets, should be really easy to reach.
The exact numbers are 214 bags * 22 bracelets / bag = 4708 bracelets; so as you see, Sarah took care of having room to loose some beads and yet the beads will be enough to make 4000 bracelets.
Of course, if you want to be sure, you should ask Sarah some questions. For example:
1) What proportion of beads are normally deffective?
2) What proportion of beads are normally lost when crafting?
So, if Sarah did not take into account those proportions she migth be overestimating the number of bracelets they can make.
Sarah's assumptions of having enough beads for at least 4000 bracelets is correct.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Sarah who has 214 bag of beads each bag has enough beads for 22 bracelets
According to Sarah, there are enough beads for at least 4000 bracelets.
Mathematically -
x[e] ≥ 4000
Actual number of beads she could make = 22 x 214 = 4708 = x[a]
Since, x[a] > x[e], we can say that Sarah's assumptions are correct.
Therefore, we can say that Sarah's assumptions are correct.

Answer:
f(- 4) = 13
Step-by-step explanation:
We require to find the value of t which makes f(t) = 13
Equating the right sides gives
- 2t + 5 = 13 ( subtract 5 from both sides )
- 2t = 8 ( divide both sides by - 2 )

if the gradient of a line is 2 and (7,2) is a point on the line, find it's equation
Answer:
y = 2x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c is the partial equation
To find c substitute (7, 2 ) into the partial equation
2 = 14 + c ⇒ c = 2 - 14 = - 12
y = 2x - 12 ← equation of line

If three dice are rolled, what chance is there
of throwing a total of 3?
Answer:
Just as one die has six outcomes and two dice have 62 = 36 outcomes, the probability experiment of rolling three dice has 63 = 216 outcomes. This idea generalizes further for more dice. If we roll n dice then there are 6n outcomes.
We can also consider the possible sums from rolling several dice. The smallest possible sum occurs when all of the dice are the smallest, or one each. This gives a sum of three when we are rolling three dice. The greatest number on a die is six, which means that the greatest possible sum occurs when all three dice are sixes. The sum of this situation is 18.
When n dice are rolled, the least possible sum is n and the greatest possible sum is 6n.

What is the equation of the line that passes through the points (4, 15) and (0, 3)?
Answer:
Y=3x+3
Step-by-step explanation:
Gradient = :[tex]\frac{y2-y1}{x2-x1}[/tex] = :[tex]\frac{3-15}{0-4}[/tex] = :[tex]\frac{-12}{-4}[/tex] = 3
Y= mx + c
y = 3x + c
Insert x and y values for first point(4,15)
15 = 3 (4) + c
15 = 12 + c
3 = c
Y=3x +3
Answer:
The equation of the line is y=3x+3
Step-by-step explanation:
y=mx+b is the y intercept form of the equation of this line.
m=slope, and we find the slope by the equation m=y2-y1/x2-x1. Plugging our number into that formula, we get m=3 - 15/ 0 - 4, or -12/-4, which simplifies to 3.
Now we can add our slope into the formula.
y=3x+b
Next, we solve for the y intercept, or b. You can use whatever point to get the answer, but I will use 4 ,15).
y=mx+b is the equation, or substituting the numbers, gets you 15=3×4+b. now solve for b: b=15-(3)(4). b=3.
now, with slope and y intercept plugged in, the final equation is. y=3x+3

y+7= 2(x-4)
y-7 = 2(x+4)
x-7 = 2(x-4)
y-4 = 2(x+7)
Answer: y+7 = 2(x-4)
Step-by-step explanation: Point slope form is y − y1 = m(x − x1), where m is the slope and (x1,y1) is one known point on the line. We are told that m= 2 and (4,-7). Therefore:
(y − (-7)) = 2(x − (4))
y+7 = 2(x-4)

Answer:
m<v= 60 degrees
m<x= 100 degrees
Step-by-step explanation:
1) First let's find the measure of angle v. Most of the time if none of the angles are known then it is impossible to find others. However, this specific triangle is an equilateral, which has special rules. We know this is an equilateral because all the sides have the same length. Equilaterals will always have angles with measures of 60 degrees. This is due to the fact that sides and angles are proportionate. Therefore, if all the sides are the same, then the angles must be as well and 180 divided by 3 is 60.
2) Then, we can find the next measurement. This triangle is isosceles. Isosceles triangles have 2 equal sides and angles. The triangle represented above has 2 congruent sides; therefore, the base triangles must also be congruent. So we know that angles Y and W are 40. To find angle X make the expression 180-(40+40). This means that angle x must be 100 degrees.
Solve 3x + 5 = 10 for x.
Answer:
x = 5/3
Step-by-step explanation:
Solve for x:
3 x + 5 = 10
Subtract 5 from both sides:
3 x + (5 - 5) = 10 - 5
5 - 5 = 0:
3 x = 10 - 5
10 - 5 = 5:
3 x = 5
Divide both sides of 3 x = 5 by 3:
(3 x)/3 = 5/3
3/3 = 1:
Answer: x = 5/3
Step-by-step explanation:
To solve for x, make it the subject of the equation and simplify:
3x + 5 = 10 [subtract five from both sides]
3x = 5 [divide both sides by three]
x = ⁵/₃
